YEAR 8 LAC SCIENCE JANUARY

1.          MAMMALS  -  Live mainly on land, have fur / hair and give birth to live young.

2.          BIRDS  -  Have feathers and wings, normally fly.  Lay eggs with hard shells.

3.          REPTILES  -  Have dry, scaly skin.  Live mainly on land.  Lay eggs with soft shells.

4.          AMPHIBIANS  -  Have smooth, moist skins.  Can live in water or on land, but have to lay their eggs in water.

5.          FISH  -  Live in water all the time and breathe using gills.  Have scaly skins and swim using fins and tails.

YEAR 8 LAC SCIENCE FEBRUARY

1.          CELL MEMBRANE  -  Surrounds the cells and controls what goes in and out.

2.          NUCLEUS  -  Controls the cell and contains instructions to make more cells.

3.          CYTOPLASM  -  The jelly-like part of the cell where chemical reactions take place.

4.          CHLOROPLASTS  -  Found only in plant cells, these capture light energy and use it in photosynthesis.

5.          CELL WALL  -  Found around the outside of a plant cell.  It is strong and supports the cell.

YEAR 8 LAC SCIENCE MARCH

1.          ACID  -  A sour substance which can attack metal, clothing or skin,  the chemical opposite of alkaline.

2.          ACIDIC  -  Describes something which is an acid.  (For example, an acidic drink).

3.          ALKALI  -  A soapy-feeling substance which dissolves grease – the chemical opposite of an acid.

4.          ALKALINE  -  Describes something which is an alkali.  (For example, an alkaline soap).

5.          INDICATOR  -  A dye which changes colour when added to an acid or alkali.

YEAR 8 LAC SCIENCE APRIL

1.          UNIVERSAL INDICATOR  -  A liquid which changes colour when acids or alkalis are added to it.  It shows whether the acid or alkali is strong or weak.

2.          pH NUMBER  -  A number which shows how strong the acid or alkali is.  (Acids have a pH 1-6.  pH 1 is very strong.  Alkalis have pH 8-14.  14 is very strong).

3.          ACID RAIN  -  Rain which has dissolved acidic gases from the air.

4.          NEUTRAL  -  Describes something which is neither an acid nor an alkali.  It has a pH of 7.

5.          NEUTRALISING  -  Adding acid to an alkali to make it neutral.  Adding alkali to an acid to make it neutral.  It show whether the acid or alkali is strong or weak.

YEAR 8 LAC SCIENCE MAY

1.          PROPERTY  -  A word to describe how a material behaves.  It can describe any piece of the material.  (For example strong, hard, soft).

2.          SOLID  -  A material which has a fixed shape, is not runny and it is not easily squashed.

3.          LIQUID  -  A material which has the shape of its container, and can be poured.  It is not easily squashed.

4.          EXPANDS  -  Gets bigger.  (Something expands when it is heated).

5.          CONTRACTS  -  Gets smaller.  (Something contracts when it is cooled).
